Sample Specification
This specification covers requirements and test methods for materials, dimensions, workmanship,flattening resistance, impact resistance, pipe stiffness, extrusion quality, marking and packaging.
Material Specification
Basic Materials
The pipe shall be made from PVC compound meeting all the requirements for cell classification 12334 as definedin specification D1784 and with minimum flexural modulus properties, tested as per ASTM Method D790, of 320,000psi (2,200MPa).
Other Requirements
Pipe Flattening
There shall be no evidence of splitting, cracking or breaking when the rounded pipe is tested according to section11.3 of ASTM F1504.
Pipe Impact Strength
The impact strength of rounded pipe shall not be less than the values in Table 1 when tested in accordance withtest method D2444 as referenced in ASTM F1504.

Extrusion Quality
The extrusion quality of the pipe shall be evaluated by the following test methods:
Acetone Immersion: The pipe shall not flake or disintegrate when tested in accordance with test methodD2152 as referenced in ASTM F1504.
Heat Reversion: The extrusion quality of the pipe shall be estimated by heat reversion method in accordancewith practice F1057 as referenced in ASTM F1504.
Flexural Properties: The flexural strength and modulus of the pipe shall be tested in accordance with testmethod D790 as referenced in ASTM F1504.
Dimensions
Rounded Pipe Diameter: The average outside diameter of the formed pipe shall meetrequirements in Table 3, +/- 1.0% when tested in accordance with test method D2122 as referenced in ASTM F1504.
Rounded Pipe Wall Thickness: The wall thickness of the formed pipe shall not be less than the valuesspecified in Table 3 when tested in accordance with test method D2122 as referenced in ASTM F1504.

Workmanship, Finish, and Appearance
The rounded and folded pipes shall be homogeneous throughout and free from visible cracks, holes, foreign inclusions, or otherdefects. The pipe shall be as uniform as commercially possible in colour, opacity, density and other physicalproperties.
Product Marking
Pipe shall be clearly marked as follows at intervals of 5ft. (1.5m) or less:
- Manufacturer’s name or trademark and code
- Nominal outside diameter
- The PVC cell classification, for example “12334”
- The legend “DR XX FOLDED PVC PIPE”
- The designation “Specification ASTM F1504”
- Length marker and liner distance label, for example “100FT” (“30.5M”)
Packaging
The full length of the PVC pipe is coiled onto a reel in a continuous length for storage and shipment. The minimum diameter of the reel drum or core shall be 48in (1,219mm).
Quality Assurance
When the product is marked with ASTM F1504 designation, the manufacturer affirms that the product wasmanufactured, inspected, sampled and tested in accordance with the specification and has been found to meetthe requirement of it.
